Electron coherent phonon coupling in Pr$_{0.5}$Ca$_{1.5}$MnO$_4$ measured with ultrafast broadband spectroscopy
Photoexcitation of single-layered La$_{0.5}$Mn$_{1.5}$MnO$_4$ has played a key role in understanding orbital ordering and non-thermal states in the manganites. However, while orbital ordering in La$_{0.5}$Sr$_{1.5}$MnO$_4$ breaks the in-plane C$_4$ symmetry, many layered manganites show much more complex phase diagrams in which orbital ordering emerges from an already symmetry-broken high-temperature phase and also exhibit additional low-temperature phases. In this work, we examine the role of …

Large Language Model-Based Uncertainty-Adjusted Label Extraction for Artificial Intelligence Model Development in Upper Extremity Radiography
Objectives: To evaluate GPT-4o's ability to extract diagnostic labels (with uncertainty) from free-text radiology reports and to test how these labels affect multi-label image classification of musculoskeletal radiographs. Methods: This retrospective study included radiography series of the clavicle (n=1,170), elbow (n=3,755), and thumb (n=1,978). After anonymization, GPT-4o filled out structured templates by indicating imaging findings as present ("true"), absent ("false"), or "uncertain." To …
